Switching report sending method, RLF report sending method and equipment

Abstract

The invention discloses a switching report sending method, which comprises the following steps that: in a switching process, a target base station acquires the position information of a source cell or the position information of a UE accessed history cell from a source base station; the target base station sends a switching report to the source base station or a base station where the UE accessed history cell is located according to the obtained position information of the source cell or the position information of the UE accessed history cell, wherein the switching report comprises an unnecessary switching report, a too early switching report or a switching report of switching to an error cell. The invention further discloses an RLF report sending method. By applying the method provided by the invention, the MRO problem can be notified to the source base station, the influence on the terminal is avoided, and the configuration of an operator is reduced, so that the MRO problem among different RATs is solved, and the system performance is improved.

Description

[0001] This case is a divisional application of an invention patent application with an application date of September 25, 2014, an application number of 201410498635.9, and an invention title of "a method and device for sending switching reports and RLF reports". technical field [0002] The present application relates to the field of mobile communication systems, in particular to a method and device for sending a handover report and a radio link failure RLF report. Background technique [0003] With the development of communication technology, the mobile communication system has developed into a System Architecture Evolution (SAE) system, figure 1 A schematic diagram of the structure of the existing SAE system is given. Such as figure 1 As shown, the system includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 101 and a core network including at least a Mobility Management Entity (MME) 105 and a User Plane Entity (S-GW) 106, and the E-UTRAN 101 is used t...

Problems solved by technology

However, there will be the following problems when sending the handover report: through the RLF indication message sent by eNB2 to eNB1, eNB1 can only know the cell identity of the source cell, but eNB1 does not know other location information of the source cell, so eNB1 cannot pass the core network. Handover report routing to source RNC

However, at present, the RAN node of the target RAT does not know the information of the source cell, nor does it know the location information of the source cell, so it cannot send the unnecessary inter-RAT handover report to the RAN node of the source RAT

[0009] In addition, for the MRO between different RATs, there may be the following problems when sending the RLF report: for example, the RNC has just switched from 3G or 2G to LTE too early The handover of UE to eNB1 is successful, and RLF occurs in UE in eNB1. When UE accesses LTE next time, UE sends UE RLF report to the eNB (such as eNB2) accessed when it accesses LTE again, and eNB2 sends RLF indication message to eNB1 , the reason why eNB1 fails to check, if it is too early inter-RAT handover, eNB1 needs to send a handover report to RNC, because the handover is performed between different systems, eNB1 needs to send a handover report to the source RNC through the core network

However, how does eNB2 know the specific information of the last cell that served the UE before the failure and how to send the UE RLF report to eNB1 through the S1 interface is a problem that the current specification does not solve
